The follow focus device for DV and HDV camcorders is compact, light and fits on the 15mm Lightweight Supports. The scale is easy to change and can also be read by the camera operator. The reference marking can be adjusted for the operator or the assistants. Gear drives and gear rings for the different lenses ensure precise adjustments and optimal use of the lensâ€™ adjustable angle. Lenses with built-in gear rings can of course also be focused.
